One feature of these developments is that there is very little friction in transitioning from a fixed background geometry to a dynamical one that reacts in response to the evolving quantum state. We demonstrate that this is essentially what is called “semi-classical" gravity (see e.g., [1]}[2]}) in the literature, and it is obtained in our framework in a very natural way. And, although such an approach has long been outright dismissed as a viable theory of quantum gravity (see e.g., [3]}), more recent work [4]}[5]} suggests that semi-classical theories of gravity cannot be totally ruled out. Put another way, the gravity theory we put forth blends together some intriguing features — quantum fields, entropy, and geometry — we ask whether this could be quantum gravity.
